I think a better approach is to look at the overall composition of the human body and calculate the number of electrons based on this using Avogadro's number.
The human body is roughly 55-60% water (18 electrons) which is easy to calculate. I'm sure with just a little googling, I can find the rest of the percentages which are carbon, nitrogen, hydrogen and then varying trace amounts of heavier elements such as iron, copper, zinc, etc.

The proton to neutron ratio REALLY doesn't matter when the total is on the order of 10^28. It isn't an order of magnitude difference and that's all that really matters.

Same thing, it's a meaningless detail when you are talking about a number that big.
